We have received from the. Meteorological Service of Canada a

report by Mr. A. J. Connor on The Temperature and Precipitation of Alberta, Saskatchewan, and Manitoba, with a set of sixteen well-executed maps showing the normal mean daily maximum and minimum temperatures for each month in the year and the rainfall in the summer months. The author points out that there are wide variations in the weather of the different districts, and that regular observations taken over long periods at many stations would be of great practical value to the farming industry on which the Prairie Provinces depend. Much has been done as these elaborate maps show, but in the newly opened northern districts, which will soon be of immense importance as a wheat- growing country, the meteorologist has still much to learn about the weather. It is good to see how thoroughly this important branch of the Dominion Government does its work. We observe that the yearly rainfall of the Prairie Provinces varies from nineteen inches near Winnipeg to thirteen inches farther west, while the normal mean maximum temperature at Winnipeg varies from 78 degrees Fahrenheit in July to 16 degrees in December, with a minimum of –2 degrees. The report deserves attention.
